PROCESS OF SEPARATING OVARIAN PRODUCT FROM ITS SURROUNDING MEMBRANE.

N0 Drawing.

To all whom it may concern:

Be it known that we, Gnonen M. Hmn'rzr This invention is in the nature of a process for separating ovarian product from its surrounding membrane. The ovarian product of female animals has long been used for medicinal purposes, especially the ovarian product of the female of the swine species. Heretofore this product has been separated from the membranous tissue of the sac in which it is inclosed by slow and tedious manual processes which naturally added materially to the cost of the product.

. After much experiment we have discovered the former di a partially mechanical process for separating this product from its inclosing membranous tissue and our invention consists in said process which we will now proceed to particularly and fully describe and afterward specifically claim. In the preparation of this product, and in our experiments which resulted in the present process, we found that the cutting up or grinding up of the membrane of the sac was very detrimental and rendered the next steps of the .process much more difiicult but we found that by burstin the sac or sacs of the ovary,

culties were avoided. We therefore provide means for bursting the sacs and our preferred means for this purpose is a machine in which the ovaries are inserted and in which there are no edges or points sufliciently sharp to cut the membrane, said machine being further provided with suitable feed and pressure mechanisms and with suitable openings through which the product may be strained out; to a large extent, from the membrane of the bursted sacs. These are the first steps of our process and while we have found .that these steps are very-efiective, we have further discovered that all of the ovarian product is not separated from the membrane and that small Specification of Letters Patent.

portions of the membrane have passed out through the strainer into the strained product. In order to remedy this defect, to re cover all of the product from the membrane, and to thoroughly separate the ovarian product from the particles of the membrane wlth which it has been mixed, we have developed the finishing step of our process which consists in placing the strained product upon a strainer, which may be of any Well-known construction but which preferably is a very rigid sheet of wire network, and manipulating or stirring this product upon this strainer by means of a comparatively stiff brush. This brush not only acts as a stirrer to press the ovarian product, which at this stage is a viscous, jelly like mass, through the finishing strainer, but also serves to brush off such of the viscous mass of ovarian product as may adhere to the small portions of the membranous tissue which is mixed therewith. The residue of this process will then consist of small pieces of membranous tissue which have passed through the first strainer but which are too large to pass through the finishing strainer, and the product is the finished ovarian product, clear of adulterations and ready for use for medicinal purposes. If it should be found that any considerable portion of the ovarian product adhered to the;: fractured membrane retained in the press' after the first straining step, this residue might be further treated by breaking it up either by hand or by any suitable mechanism, and subjecting it to the finishing process of strain- Patented-Dec. 7,1915.

ing and brushing, which treatment would obviously be included within the scope of our invention but would only be availed of in case of the adherence of a suificient quantity of the ovarian product to the membranous tissue of the sac to make it profitable to submit this residue to the finishing straining and brushing step.

, Our invention is intended to include within its scope the process set forth in our claim, including the finishing step, whether the whole or any portion of the'process is carried out either manually or mechanically and it will be obvious to those skilled in the art that slight changes and variations may be made from the process described without departing from the spirit and scope of the invention.

Having thus fully described our invention 5 what we claim as new and desire to secure by Letters Patent of the United States is- The process herein described of separatbrane which comprises the feeding of the 10 ovaries into an inclosed space and successively applying to the sacs a bursting pressure whereby the contents are extruded and permitted to freely escape.

In testimony whereof we aflix our signatures' in presence of two witnesses.
